To all whom it may concern:

Be itknown that I, FRIEND A. ALLEN, a citizen of the United States.residing at Granger, in the county of Scotland and State of Missouri,have invented certain new and useful Improvements in Pumping Apparatus,of which the follow-ing is a speciiication, reference being had thereinto the accompanying drawing.

This invent-ion relates to that class of pumping apparatus in whichwater is raised from a well or other deep placeby means of compressedair alternately delivered to a pair-of cylinders submerged in the waterin the well.

The invention has for its object to provide an improved apparatus ofthis kind which will be simple in construction and effective inoperation and so constructed and arranged that the operation will becontinuous and spasmodic action avoided.

Referring to the accompanying draw- 1ngs:Figure 1 is a view inelevation, partly broken away and in section of a pumping apparatusconstructed in accordance with this invention, and shown in operativeposition in'connection with a well. F1g.'2 1s a plan new of an airengine employed 1n connection with this invention. F1g. 3 1s a detailside vlew, partly in longitudinal section, of a portion of the valveoperating mechanism connected with the air engine. Fig. 4 is an enlargeddetail view of a portion of the frame of the engine and a portion of apair of valve operating rods operated by the engine. Fig. 5 is a detailview of a pair of gear wheels operated by the engine. Fig. 6 is a detailview of a pair of rods partly shown in Fig. 4, in cross section, andtheir connecting links. Fig. 7 is a detail view in cross section of oneof said rods shown in Fig. 4. Fig. 8 is a block forming a part of one ofthe cylinder heads ofthe air engine.

and means for conveying the water alternately drawn from said cylindersto the point of supply.

In carrying out the invention, an air. engine is provided mou'nted in asuitable frame Lhaving a cylinder 2, a piston rod 3, a cross head +1,and a crank rod 5 pivoted to the cross head atone end and connected atits other end to the crank shaft 6. The heads of the cylinder 2 are eachformed of a pair of rectangular blocks 7 and S secured together in anysuitable manner. the blocks 8 having a vertical passage way 9 open atthe top and opening at its lower end laterally into a chamber 10. Theblock 7 is formed with a transverse passage way 11, as shown in Figs. 9and 14, which opens at one end into the cylinder 2 and at its other endinto the chamber 10 in the block 8. The block 7 is formed on one sidewith a pair of semi-circular projections 12 located one above anotherand spaced apart so as to provide guides for a valve, the straight edges13 of the semi-circular projections 12 forming said guides between whichis mounted a valve 14 consisting of an oblong rectangular block havingproject-ing laterally from one side an oblong rectangular block 15 whichis located transversely in the passage Way 11,'as shown in Figs. 10 and11, and is slidable lengthwise therein. Projecting laterally from theprojection 15 is a valve stem 16 which projects through a hole 17 in theblock 7 and beyond the same. The valve 14 is provided with a transverseopening 18 which, by the movement of the valve 14, is brought into andout of alinement with the passage way 11 thereby opening and closingsaid passage way. The inner end of the valve stem 16 has mounted thereona nut 18 which is movable into and out of a socket 19 in the block 7 asa valve 14 is moved backward and forward. The valve stem 16 is provided.at its outer end with a vertical pin 20, as shown in Fig. 3. When theblocks 7 and 8 are secured together, the valve 14 is movable on theguides 13 to open and close the communication of the passage way 11 withthe chamber 10 in the block 8. Referring to Figs. 10 and 11, the valve14 is shown in closed position in Fig. 10, and in open position in Fig.11 in connection with the opening 11.

The. inlet valves 14 are aiternately opened and closed by means of areciprocating slide 21 mounted in guides 22, the pins 20 projecting upthrough slots 23 in the slide 21 and being acted upon by the slottedslide 21 in its reciprocating movement. The slide 21 is pivotallyconnected at one end to a rod 24, having at its other end an enlarge-1ment 24' mounted upon the eccentric 25 secured to the crank shaft 6.Connected with the vertical openings 9 in the blocks8 of the heads ofthe cylinder 2 are'the depending ends 26 of a ipe 27, on which ismounted a three-way ctihpling joint 28 from which leads a pipe 29connected with a compressed air storage tank 30 which is supplied withcompressed air from a compressor not shown.

Connected with the three way coupling joint 28 are pipes 31 and 32formed of pipe sections coupled together so as to extend a considerabledistance to permit the cylinders 33 and 34 connected respectively withthe pipes 31 and 32 to be suspended in thewater of a well 35, as shownin Fig.

1. The pipe 29 is provided with a globe valve to regulate the flow ofair through the pipes 31 and 32. A globe valveserves as a throttle valveto control the supply 'of air to the cylinder 2. Each of the cylinders33 and 34 is provided in its bottom with an inlet valve 36 of anysuitable well-known construction whereby water may be admitted to thecylinders from the well. Connected with the 'top of the cylinder 34 is apipe 38- and with the top of the cylinder 33 is a pipe 37, which are forthe purpose of permitting the escape of air from the cylinder whennecessary.

' Located in the pipe 31 is a valve casing 39 containing a valve and inthe pipe 32 is a valve casing 40 containing a valve. The valves in thecasings 39 and 40 are connected to a rotary rod 41 so as to alternatelyopen and close the pipes 31 and 32 when said rod is oscillated. The pipe27 takes only enough air to run the engine, the main part of the airpassing alternately through the pipes 31 and 32. Mounted on the rod 41are tappe'ts 42, located at a right angle to each other as shown inFigs. 1, 4, and 7, and adapted to be alternately struck to oscillate the.rod 41 by means of a pin 43 depending from a horizontal toothed wheel44 meshing with a toothed wheel 45, as

shown in Fig. 5, the shafts of said toothed wheels being mounted in asupport 46, and the shaft of the wheel 45 having at its upper end thetoothed wheel 47 which meshes with a worm 48 mounted on thecrank shaft6. Located onone end of the crank shaft 6 is a balance wheel 49 whichmay be connected by a band with a suitable driving.

power and on the other end of the crank shaft 6 is a balance wheel 50.Located adjacent to and parallel with the rod 41 is a rotary rod 51which is connected at one end to a valve in a valve casing mounted onthe pipe 37 and at its other end to a valve in the valve casing 53 andmounted on the pipe 38, the valves of said casings operating toalternately open and close by means of the rod 51 which is connectedwith and operated by the rod 41 by means of a pair of links 54 looselyconnected at theirends to rings 55 mounted on the -rods 41 and 51.

'Mounted on each ofthe cylinders 33 and 34 is a vertical pipe 56 for thedischarge of water from the cylinder, each of said pipes 56 beingprovided with a valve 58 at the-upper end of said pipe which isconnected by a branch pipe connection 59 with the pipe 60 which leads toa point of discharge as indicated partly by dotted lines. The airdischarged from each of the cylinders through the pipes 37 a-n'd'38 whenthe valve in the casing 52 or 53 is open is conducted to the open airthrough one of the pipes 61, shown in dotted lines, in Fig. 1.

The operation of the apparatus is as follows :In Fig. 1 the cylinder 34is shown as having water admitted thereto and the valves in the valvecasings 39 and 53 are open and the valves in the valve casings 52 and 40are closed. By means of this arrangement of the valves, the engine beingin action, compressed air is sent through the pipe 31 and drives thewater from the cylinder 33 up through the pipe 56 and'through in thecasings 39 and 53 and opening the valves in the casings 52 and- 40. Bymeans of this alternative operation of the valves together with thealternative action of the valves of the engine compressed air is alternatively delivered through the pipes 31 and 32, respectively, and wateris alternately admitted to the cylinders 33 and 34, discharged therefromand carried to the source of supply. 7

It is obvious that many minorchanges may be made in the form andconstruction of this invention without departing from the essentialprinciples thereof. I do not, therefore, desire to confine myself to theexact form herein shown and described but an air engine, of a waterreceiving chamber with'an inlet valve mounted on the end of each of saidbranch pipes and'adapted to be suspended within a well, a valve in eachof said. branch pipes, an air escape pipe connected with the top' ofeach of said cylinders, a valve in each of said air escape ipes, a waterdischarge pipe connected withthe top of each of said cylinders, a rotaryrod connected with said valve in the branch pipes, a second rotary rodconnected'with each valve in the air escape pipe, a link connection'between said rods, apair of tappets on the first named rod, a toothedgear wheel having a depending pin adapted to successively engage saidtappets and alternately operate the same, a second toothed wheel meshingwith said toothed wheel, a toothed wheel on the opposite end of theshaft.of

said second toothed wheel, and a worm meshing with said last namedtoothed wheel,

and mounted on the crank shaft of the en-' gine.

In testimony whereof I hereunto aiiix my signature in presence of twowltnesses.

r FRIEND A. ALLEN.
